I'm studying for "Oracle Database SQL Expert". There is a whole section about regular expressions:
Regular Expression Support
[ ] Using Meta Characters
[ ] Regular Expression Functions
[ ] Replacing Patterns
[ ] Regular Expressions and Check Constraints


Are these the same regular expressions used in Java? If not, how do they differ?

Thanks

Oracle's regular expressions are based on the POSIX Extended Regular Expressions (ERE). Java adds more functionality to it, but I think the basic syntax is the same. You'll find some comparative information here.
